BACKGROUND OF THE INVENTION

[0001] The present invention is related to a hanging hook structure. When hooking an article, it is unnecessary to keep pressing the press rod with a finger. The hanging hook is assembled by means of tight fit of tenons and the mortises which are hidden in the casings of the hanging hool. Therefore, no locating structure is exposed to outer side so that the hanging hook has a tidy appearance.

[0002]FIG. 1 shows a conventional hanging hook having a hook body 10 and a movable block 11 riveted with the hook body 10 by a rivet 12 and resiliently pushed by a compression spring 13. The hook body 10 is arched and formed with an opening on front face. A hooking section 101 is formed on inner side of the opening. A lower portion of the hook body 10 is formed with a receptacle 102 and a rivet hole in front of the receptacle 102. A ring body 103 is pivotally connected with lower end of the hook body 10 via a short cylindrical shaft. The lower section of the movable block 11 is inserted into the receptacle 102 and pivotally connected with the hook body 10. The rear face of the movable block 11 is provided with a locating boss 111 on which the compression spring 13 is fitted and located. When not used, the upper end of the movable block 11 is leant against one side of the opening of the hook body to block the opening. When used, a user presses the movable block 11 with a finger to pivotally inward rotate the movable block 11 about the rivet 12. Accordingly, the compression spring 13 is compressed between the movable block 11 and the hook body 10 and the opening of the hook body 10 is open. At this time, the hooking section 101 of the hook body 10 can hook an article through the opening. Thereafter, the movable block 11 is released from the pressing, whereby the compression spring 13 resiliently restores the movable block 11 to its home position to again block the opening of the hook body 10. Under such circumstance, the article is encompassed by the hanging hook without detachment therefrom.

[0003] The above conventional hanging hook has some shortcomings as follows:

[0004] 1. When hooking an article, the finger must keep pressing the movable block 11. This makes it difficult and inconvenient to hook the article.

[0005] 2. The hanging hook has polished surface so that when keeping pressing the movable block 11, the finger tends to slip away and it is necessary to again press the movable block 11. Therefore, it is hard to quickly and easily hook the article.

[0006] 3. The movable block 11 is pivotally connected with the hook body 10 via the rivet 12. The rivet 12 is exposed to outer side and leads to poor appearance of the hanging hook.

SUMMARY OF THE INVENTION

[0007] It is therefore a primary object of the present invention to provide a hanging hook structure. When hooking an article, it is unnecessary to keep pressing the press rod with a finger so that it is easy, convenient and quick to use the hanging hook for hooking an article.

[0008] It is a further object of the present invention to provide the above hanging hook structure by which when hooking an article, it is unnecessary to keep pressing the press rod with a finger so that the finger is not likely to slip away from the polished surface of the hook body. Therefore, the hooking operation can be quickly and truly performed.

[0009] It is still a further object of the present invention to provide the above hanging hook structure in which the hook body and the casings are assembled with each other by means of tight fit of the tenons and the mortises which are-hidden in the casings. Therefore, no locating structure is exposed to outer side so that the hanging hook has a tidy appearance.

[0010] The present invention can be best understood through the following description and accompanying drawings wherein:

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0015] Please refer to FIG. 2. The present invention includes a hook body 30, two casings 40 mated with each other, a press rod 50, a compression spring 60 and a restoring spring 61. The hook body 30 is arched and formed with an opening 31 on upper front face. A hooking section 32 is formed on inner side of the opening 31. A slide stem 33 downward extends from lower side of the hook body 30. One side of the slide stem 33 is formed with a plane attaching face 331. An upper rear side of the slide stem 33 is formed with an escape recess 332. A stop block 333 is formed under the escape recess 332. The middle of front side of the slide stem 33 is formed with an insertion notch 334. The center of lower end of the slide stem 33 is formed with a restoring spring pushing cavity 335 under the insertion notch 334. The casings 40 are arched and oppositely mated with each other. The upper front side of each casing 40 has an upward extending stop block 41 corresponding to the opening 31 of the hook body 30. The inner side of the casing is cut with a slide channel 42 and a push channel 43 communicating with the slide channel 42 to form a cross shape. The upper end of one side of the slide channel 42 is provided with a projecting stop block 421 (or a dent 421′ corresponding to the stop block 421). The lower end of the slide channel 42 is formed with a restoring spring retaining section 422. The front section of the push channel 43 in front of the slide channel 42 is formed with a compression spring retaining Section 431. The rear section is provided with a diaphragm 432 dividing the rear section into a large receiving space 433 and a small receiving space 434 at the opening of the push channel. The diaphragm 432 is formed with an arched notch 435. The inner faces of the casings 40 are formed with several mortises 44 and tapered tenons 44′ surrounding the slide channel 42 and the push channel 43. The rear end of the press rod 50 via a small diameter section is connected with a press head 51. The middle portion is cut with an engaging recess 52. The front end of the engaging recess 52 is formed with an engaging block 53. The front end face of the press rod 50 is formed with a compression spring retaining face 54.

[0016] When assembled, as shown in FIG. 3, the restoring spring 61 is first placed into the slide channel 42 of one casing 40 with one end abutting against the restoring spring retaining section 422. Then the slide stem 33 of the hook body 30 is placed into the slide channel 42 of the same casing 40 with the restoring spring pushing cavity 335 abutting against the other end of the restoring spring 61. The stop block 421 of the casing 40 is received in the escape recess 332 to avoid the slide stem. Then, the hook body 30 is downward pressed to align the insertion notch 334 with the push channel 43 of the casing 40. At this time, the restoring spring 61 is compressed. The press rod 50 is placed into the push channel 43 from one side of the casing 40. The press rod 50 is passed through the arched notch 435 and stopped by the diaphragm 432. The front section of the press head 51 is received in the small receiving space 434, while the rear section of the press head extends out from the rear face of the casing 40. The engaging recess 52 of the press rod 50 is attached to the attaching face 331 of the hook body 30. The engaging block 53 is right engaged in the insertion notch 334 of the hook body 30. Then, two ends of the compression spring 60 are respectively leant against the compression spring retaining section 431 of the casing 40 and the compression spring retaining face 54 of the press rod 50. The engaging block 53 of the press rod 50 is pushed by the compression spring 60 to truly engage in the insertion notch 334 of the hook body 30. Also, the hook body 30 is stopped by the engaging block 53 from upward sliding. Finally, the other casing 40 is mated with the casing 40 and the tapered tenons 44′ thereof are forcedly tightly fitted into the mortises 44 so as to firmly associate the two casings 40 with each other. After the two casings 40 are mated with each other, the stop blocks 41 thereof block the opening 31 of the hook body 30.

[0017] In use, as shown in FIG. 4, a user's finger presses the press head 51 to move the press rod 50 forward. At this time, the compression spring 60 is compressed. When the engaging block 53 of the press rod 50 is totally moved out of the insertion notch 334 and disengaged therefrom, the hook body 30 is free from any stopping force and resiliently pushed by the restoring spring 61 to abruptly bound upward. At this time, the insertion block 53 is restricted by the front face of the slide stem under the insertion notch 334 from bounding back. When the stop block 333 of the upward bounding hook body 30 abuts against the stop block 421 of the casing 40, the hook body 30 is immediately stopped from upward bounding. Under such circumstance, the opening 31 of the hook body 30 is opened. At this time, the hooking section 32 can hook an article. After hooked, the hook body 30 is again pressed by the finger to downward slide. When the insertion notch 334 is again aligned with the engaging block 53, the engaging block 53 is resiliently pushed by the compression spring 60 to again slide into and engage with the insertion notch 334. Also, the press rod 50 is restored to its home position. At this time, the hook body 30 is restricted from moving upward and the opening 31 is blocked and the article hooked by the hooking section 32 is prevented from detaching from the hook body 30.

[0018] The present invention has the following advantages:

[0019] 1. When hooking an article, it is unnecessary to keep pressing the press rod with a finger so that it is easy, convenient and quick to use the hanging hook for hooking an article.

[0020] 2. When hooking an article, it is unnecessary to keep pressing the press rod with a finger so that the finger is not likely to slip away from the polished surface of the hook body. Therefore, the hooking operation can be quickly and truly performed.

[0021] 3. The hook body and the casinos are assembled with each other by means of tight fit of the tenons 44 and the mortises 44′ which are hidden in the casings. Therefore, no locating structure is exposed to outer side so that the hanging hook has a tidy appearance.
